CARL MUEHLEISEN, OF BERLIN, GERMANY, ASSIGNOR TO THE MERGEN- TI-IALER LINO'IYPE CO., OF NEIN` YORK.

LlNOTYPE-MACHINE'..

SPECIFICATION forming part of Letters Patent No. 679,479, dated July 30, 1901,

Application filed December 28, 1900. Serial No. 41,384. (No model.)

To all whom, zit may concern.-

Be it known that I, CARL MUEHLEISEN, residing at Berlin, Germany, have invented a new and useful Improvement in Linotype- Machines, of which the following is aspecication.

My invention has reference to linotype-machines in which metal matrices containing letters or other characters are held in storage in a magazine, from which they are released in the required order by finger -keys and thereafter assembled in line with spacing or justifying devices, the composed lines thereafter presented to the edge of a slotted mold into which molten metal is delivered to form a slug or linotype, and finally the matrices returned through a distributing mechanism to the magazine from which they started. A machine of this general organization is to be found in Letters Patent of the United States to Mergenthaler, No. 557,000.

The aim of the present invention is to produce a machine which will be smaller, lighter, and cheaper than those now in general use and at the same time adapted for all ordinary classes of composition.

In carrying my invention into effect I employ matrices of improved form having shoulders on one edge only and having a single set of distributing-teeth arranged obliquely across the upper end. Heretofore matrices have been made with a notch or recess in the upper end and with distributing-teeth on one or both walls of the notch. My improved matrix, as shown in the present drawings, is made without a notch or recess and with the upper end inclined or beveled from one side or edge toward the other and with distributingteeth on this outer or exposed edge. The construction is advantageous because of its cheapness, of the ease of manufacture, and of the fact that it gives an increased surface in proportion to the size of the matrix for the distributingteeth, so that the teeth may be made larger andstrouger than usual. These matrices I employ in an upright slotted magazine in connection with key mechanism of simplified construction. The devices for transferring and clamping the line are also of special and simplied construction. The mold instead of being mounted in a rotary Wheel is mounted in a carrying-arm having a vibratory motion around a center, whereby the base of the slug is carried from the casting position past a stationary trimming-knife and presented opposite the ejector, by which it is delivered from the mold. The line ot' matrices, including spacers, is carried upward by an elevator from the casting position to the level of the distributer, into which the matrices are delivered one at a time, while the spacers are permitted to escape and travel down a guide or conductor to their magazine. The distributer-rail is toothed longitudinally on its under side to engage the matrices on one side, andthe matrices are carried along the rail by an endless carrier.

Figure l is a front elevation of my machine. Fig. la is a detail view of the line resisting and transferring device, the parts being in the position occupied during the composition of the line. Fig. lb is a view of the same parts in the position which they occupy during the transfer and delivery of the line. Fig. 2 is an elevation of the same from the left side, the mold, the mouth of the pot, and adjacent parts being shown in vertical section on the correspondingly-numbered line of Fig. l.

Fig. 43 is a top plan view of the parts shown in the preceding iigure. Fig. 44 is an outline elevation looking from the front and illustrating lmore particularly the mechanisms for clamping the line of matrices in front of the mold, for effecting justication, for shifting the matrixline from the elevator into the distributer, (itc. Figs. 45 and 46 are respectively a top plan View and a front elevation of the support and elevator for the matrix-line and mechanisms for operating the same.

Referring to the drawings, A represents a rigid main frame, which may be of the form and construction shown in the drawings or of any other form and construction adapted to give support to the various operative parts hereinafter described.

B represents an upright fixed magazine into which the matrices are delivered at the top by the distributing mechanism and from which they are delivered at the foot one at a time preparatory to their assemblage or composition in line. This magazine is preferably constructed in the manner shown in det-ail in Figs. 15, 16, and 17, consisting of a metal plate containing in its forward lface a series of vertical grooves or channels Z9, differing in width according to the width of the matrices they are to contain and each intended to carry a row or column of matrices C, standing on end one upon another. The front of the magazine is closed by a glass plate b, fixed thereto and serving to hold the matrices in the grooves and at the same time to give the operator a view of the entire interior of the magazine and the matrices therein.

For the purpose of discharging the matrices one at a time from the magazine I mount at the lower end of each magazine-channel an escapement D, consisting of two pawls d and d', connected to opposite ends of an operating-lever d2, whereby they are caused to project alternately into the magazine. A spring d3, connected with the escapement-lever, tends to hold the parts in the position shown in Fig. 15, with the lower pawl pro jected into the magazine to sustain the bottom matrix and the upper pawl withdrawn. The escapement is operated by a 1inger-key d4, jointed at its upper end to the lever d2 and having midway of its length a projection or fulcrum-point d5, which bears loosely against the front of the magazine. When a {ingerkey is depressed, it actuates the lever d2, reversing the position of the pawls, as shown in Fig. 16, and permitting the lower matrix to escape, while the one next above is held bythe upper pawl. Then the keyis released, the spring causes the escapement members to resume their original position, allowing the next matrix to descend to the lower pawl preparatory to its discharge by the next action of the escapement. It will be observed TOO IIO

that the entire series of finger-keys, together with the front plate against which they bear, are permitted by reason of their jointed connection to the escapement to swing upward and forward, as indicated in dotted lines in Fig. l5, and this in order to give access to the channels or passages through which the matrices pass after leaving the lower end of the magazine proper. The matrices, escaping from the magazine, pass downward through guide-channels E and are received on an inclined conveyer-belt F, traveling around pulleys fat its ends and serving to carry the matrices downward and forward to the left and to deliver them into a slotted assembler G in front of the vertical angular wheel H, by which they are pushed forward one after another and assembled in line, this wheel serving to push the line bodily forward in order to leave room for the admission of each matrix as it descends in essentially the same manner as in the commercial linotype-machine of the present day.

The spacing or justification of the matrixlines is effected by means of a series of spacers I in the form of stepped wedges, such as shown in Fig. 13 and hereinafter described in detail. These wedges are held in storage above the matrix-assembler in a magazine K. (Shown in cross-section in Fig. 22.) The spacers are formed at their upper ends with hooks,where by they are held in suspension on theinclined magazine-rail it. The foremost spacer stands directly over the finger-key L, commonly termed the space-keyjwhich is pivoted at its middle and drawn downward at its rear end by a spring Z. Then the forward end of this key is depressed, its rear end lifts the foremost spacer until its hooked end is clear of the lip or shoulder at the end of the distributer-rail, whereupon the spacer is pushed forward by those behind it and released, so that it falls by gravity into the assembler between the preceding matrix and the star-wheel H, this action being very similar to that in the ordinary linotype-machine- As the line of matrices and spacers is composed and increases in length in the assembler it must of course be held in compact form, and for this purpose I propose to employ a yielding resistant of any suitable character. In the form shown in the drawings (see Figs. 1 and l1) this resistant consists of a finger M, pivoted to a frietional slide m, arranged to slide right and left on the assembler Gr, the finger M being held normally downward in position opposite the matrices by a spring m', extending from the slide to the lower end of the finger M. A second lever m2 is also pivoted to this slide and connected therewith by a slot and pin. This finger m2, serving as a transfer device, is so formed and arranged that when it is turned down to the right by hand its end will close behind or to the right of the matrix-line, as shown in Fig. lb, so that in moving the whole device to the left by hand the operator may transfer the composed together.

line through the channeled assembler G and into the elevator N, to be presently described. After the line is thus transferred the operator, pressing on the upper end of the detent-finger M, lifts it clear of the matrix-line, so that the carrier and'detent may be returned to the right to their original positions preparatory to the composition of the nextline. During the composition of the line the lever or finger m2 stands in the upright position out of the path of the matrices advancing to the line. It is to be understood that this particular form of resistant and transfer device is not of the essence of my invention and that it may be modified at will.

After the line of matrices and spacers has been transferred, as above mentioned, it must be first lowered into position to coperate with the mold and thereafter lifted to the distributing mechanism at the top of the machine, and it is the object of the elevator N to effect these movements of the line. This elevator is constructed, as shown in Figs. 3, l0, 23,V 24, 25, and 27, of the upper and lower members a and n', mounted to slide vertically on the guide n2 and connected by a vertical spring n3, which tends to draw the two parts The elevator as a whole is slotted vertically from the right-hand side in order to permit the matrices and spacers to be pushed into it by the carrier already alluded to. The lower member n presents an inner or rear side, as shown in Fig. 24, a vertical face to bear against the lower edges of the matrices, and also an upper edge, on which the hooks of the spacers engage to hold them in position in the line. The upper member 'n normally extends downward behind the member n and behind the line of matrices and spacers, as plainly shown in Fig. 24, its front face being recessed to admit the rear edges of the matrices, which extend beyond the spacers, as shown. I It will thus be seen that when the parts are in normal condition the matrices and spacers are held in line between the parts oz and frt, the matrices engaging in the plate n, so that their vertical movementis prevented, While the spacers are free, so that they may be thrust up through the matrix line in order to present 4their thicker portions therein, and thereby effect the justification of the line or, in other words, its elongation to the predetermined length, as hereinafter more fully explained. After the composed line is received in the elevator N the latter is lowered from its original or composing level (shown in Figs. l and 23) to the level of the mold O and casting-pot P, (see Figs. 2, lO, and 37,) preparatory to the casting of the slug in the mold and against the line of matrices. The mold O, havingaslot therethrough from front to rear of the dimensions of the required linotype, is mounted in one end of an arm o, having both a vertical vibration and a slight motion in a fore-andaft direction, as illustrated in detail in Figs.

The mold-carrying arm or 30, lo, and In.

IOO

IIO

lever o has at its middle a supporting-sleeve or hub mounted on a horizontal shaft o',

' around which the arm is free to vibrate vertically and on which it is also permitted a slight sliding motion in a fore-and-aft direction. After the elevator N lowers the line of matrices to its position in front of the mold the latter is pushed forward through an opening in the side of the elevator until its front face iits into and against the matrix-line, as shown in Fig. 10, the matrices and spacers serving to close the front of the mold to which the matrix characters are presented.

The melting-pot P, in which a supply of molten type-metal is maintained and from which it is delivered into the mold to form the slug or linotype, has supporting-legs mounted .on a horizontal shaftp, around which the pot vibrates in order to bring its delivery-mouth against and withdraw it from the rear face of the mold. The pot is provided with the usual delivery spout or mouth and with an internal pump well or cylinder containing a piston p2, the depression of which serves to effect the delivery of the molten metal through the pot-mouth into the back of the mold in the manner common to all linotypemachines. After the slug is cast in the mold the pot is retracted, the mold drawn rearward from the matrices, and the mold carried upward by the vibration of its supporting-arm past a stationary knife Q, (see Figs. 39 and 40,) which serves to dress off the base of the slug Hush with the rear face of the mold, whereby the slug is brought to the required type height. Continuing its motion beyond the base-trimming knife, the mold stops in the rear of two parallel knives R R, which are fixed to a portion of the main frame at a distance apart equal to the thickness of the required slug. While the mold stands at rest, sustaining the slug in line with the passage between the knives, a horizontal reciprocating ejector-blade S, suitably guided in the frame, advances from the rear and, acting on the base of the slug, drives it forward out of the mold and into the path of a vibrating lever T, mounted on a horizontal pivot t and urged to the left by a spring t'. An inclined surface on the ejector-arm raises this lever T out of the path of the slug, and when the ejector retreats, releasing the lever or slug-carrier T, the latter swings to the left under the influence of the spring and pushes the slug or linotype into the galley V, adding it to the line therein assembled and pushing the line bodily to the left to make room for the next slug. It will of course be understood that motion may be imparted to the foregoing members by any suitable mechanism. In the present instance, however, the mold-arm receives its vertical motion from a cam o2, mounted on the main horizontal shaft U and acting on the antifriction-roller on the rear end of the arm to effect the elevation of the mold. A spring 03, connected to the mold-arm, as 'shown in Fig. 39, serves to draw the mold down when relieved from the action of the lifting-cam. The fore-and-aft motion of the mold to close it against the matrices and to withdraw it from the slug and matrices is effected, as shown in Figs. 39 and 40, by a peripherallygrooved cam o5, also secured on the main shaft U and engaging a projection o6 on the sleeve of the mold-lever, so that as the cam revolves the lever and mold are moved forward and backward at the proper times. The ejector-blade S, mounted in a fixed guide, is connected by link s to lever s', mounted midway of its length on pivot s2 and acted upon at its rear end by a side cam S3, also mounted on the main shaft U, so that as the cam rotates it effects at the proper time a positive forward motion of the ejector, which is drawn rearward when the cam ceases its action by a spring s4, extending from the ejector-lever s to the main frame.

When the composed line after being transferred from the assembling-point into the elevator N is lowered by the latter to the operative position in front of the mold, means must be provided to limit the elongation of the line, or, in other words, to confine the line of matrices endwise, so as to limit its expansion when the spacers I are pushed up ward through the line, so that all of the lines may be of the same length. For this purpose I propose to use in the machine two jaws or abutments W and W', located on the machine-frame forward of the position occupied by the mold when in its casting position. The elevator N straddles these jaws while lowering the matrices and spacers between them in a manner substantially the same as in the linotype-machines now in general use. These jaws may be stationary or movable.

After the line has served its purpose in front of the mold-that is to say, after the slug has been cast and the mold retractedthe elevator N rises, lifting the line to the top of the machine preparatory to its distribution. The upward-and-downward motion of the elevator N is effected by a pitman a5, connecting it with a long lever or arm m6, having a hub mounted on a horizontal axis and provided with a second arm fnf", one end of which is acted upon bya lifting-cam 'nS on the main shaft, the cam being of such form that the elevator is alternately raised and lowered and permitted to remain at rest during the casting operation and during the delivery of the matrices therefrom into the distributer. As the rising elevator N approaches the limit of its upward movement its lower member 'it' comes in contact with the lower edge of a fixed vertical plate n, (see Figs. 25 and 26,) whereby the movement of the lower member n', on which the spacers I are suspended, is arrested, so that the member 'n' stands flush with the upper end of the inclined rail 7a, leading downward to the magazine or holder f'or the spacers. Although the lower member n of the elevator supporting IOO IIO

the spacers is arrested, as above described, the upper member n is permitted by reason of the spring connection to continue its upward movement, whereby the matrices C are lifted away from the spacers and away from the lower member n/ of the elevator, as shown in Figs. 25 and 26, the plate ng serving at this time to keep the matrices in contact with the member n, so that they may be lifted, as shown, entirely above the spacers and to a suitable level for transference to the distributer. It will be observed that the spacers left behind the matrices at a lower level are free to slide laterally onto the rail k, down which they pass by gravity to the magazine from which they started.

The distribution of the matrices to their proper magazine-channels is effected mainly by a series of teeth c4, formed on the upper ends of the matrices and arranged to engage with corresponding teeth on the lower edge of a fixed distributer-bar X, lying over the upper end of the magazine and across the mouths of the channels therein. Each character in the keyboard is represented by a special arrangement of teeth on the corresponding matrices. All matrices bearing the same character have the same arrangement of teeth; but a matrix bearing any given character differs as to the number or the arrangement of its teeth, or both, from a matrix bearing any other character. In like manner the distributerbar has its series of teeth cut away over each magazine-channel, so that at this point the number or relation of the teeth is different from those at any other point in the length of the bar, this mode of permuting the teeth of the matrices and the distributer-bar being analogous to that set out in United States Letters Patent No. 347,629 to Ottmar Mergenthaler, dated August 17, 1886. My improved matrices, however, differ from those shown in the Mergenthaler machine in that they are not notched in the upper end to straddle the distributer-bar and provided with two opposing sets of teeth to engage the bar on opposite sides. On the contrary, each of my matrices is beveled across the upper end from the front to the rear side and has a single series of distributing-teeth, which may therefore be made much larger and without that extreme precision as to size necessary in the Mergenthaler construction. My distributerbar instead of being made of V form at the lower end' has a Hat lower surface, on which the longitudinal distributing teeth are formed; but in order that these teeth may properly engage the vertical matrices and hold them in suspension the bar is in-crosssection inclined forward toward its top, as shown particularlyin Figs. 29 and 32, so that its lower toothed edge stands at an inclina tion to the horizontal and in position to engage the teeth of the matrices which are held in contact therewith by the vertical surface of the elevator member n and by other xed surfaces n10, (see Figs. 29 and 30,) forming the continuation of this plate, extending across the machine above the magazine. In other words, the toothed angular tops of the matrices enter the angular space between the lower inclined edge of the distributer-barand the Vertical surface of the adjacent plate n10.

After the matrices have been lifted in the elevator for transference to the distributer, as before referred to and as shown in Figs. 25 and 26, they are carried forward to the right to a point immediately under the distribnter-bar by a horizontally-reciprocating slide connected by link w' to the upright lever x2, moved in one direction by cam m3 and in the opposite direction by a retractingspring Q04. The forwardf-that is to say, the right-hand-end of the matrix-line ispressed into the path of the rising-and-falling liftingfinger x5, (see Figs. 29, 33, 34, and 36,) the upper end of which is formed to engage the foremost matrix and lift it away from its companions and into the path of one of the teeth :r6 on a horizontal endless belt 037,'the teeth of this carrier-belt serving to carry the separated matrices forward, one after another, along the distributer-bar until they reach points immediately over the corresponding channels in the magazine, at which points the teeth of the matrices and those of the disltributer-bar have such relation to each other that the matrix is released and permitted to descend by gravity into the magazine. The

IOO

lifting-finger x5 is pivoted to one end of an A angular lever v8 (see Figs. 28, 29, 33, dac.) and is drawn backward by a spring 009, where by it is held in engagement with the matrices. The lifter-operating lever ses is mounted on an axis m10, inclined from the horizontal in a foreand-aft direction, as plainly shown in Figs. l, 2, 29, 32, rbc., so that the matrix is lifted from its support with a forward movement into engagement with the distrubuter-bar. It will be understood, of course, that the foremost matrix at the instant of being lifted is beyond the end of the guides which sustain the remaining line of matrices, so that it may be lifted past the end of these guides into engagement with the bar, as described. The lifter-lever m3 is acted upon at its upper end by a cam x to effect the depression of the lifting-finger and is moved in the opposite direction to elevate the finger and matrix by a spring m12. (Shown more particularly in Fig. 33.) lt will be observed;l that the lifting-linger is notched or forked at the upper end to permit the forward passage of the carrier-teeth on the belt, so that the tooth engaging the matrix from the left may carry it forward to the right before the linger completes its descent. The pulley 6013, which sustains and drives the carrierbelt, receives motion (see Figs. 2S and 29) through a gear-wheel m14, fixed on its shaft and receiving motion in turn from the pinion m15 on the shaft which carries the lifter-actuating cam already referred to. This shaft IIO receives motion through a driving-pulley w16, secured to its end and receiving motion in turn from a continuously-acting driving-belt .1:21, acting with moderate friction thereon, so that it may slip when the pulley is stopped, as hereinafter described. The shaft carrying pulley :1:16 on pinion x15 is also provided with a toothed wheel or disk w17, fastened thereon. This shaft is mounted in an arm w19, swinging around the axis of gear-Wheel fr as a center and having a lip or shoulder in its lower edge near the outer end. An angular dog or lever m18 is pivoted to the frame in such position that its opposite ends may be engaged alternately with the shoulder of the arm w19 and with the teeth of the wheel fr, A spiral springo, acting on this arm, connects the dog m18 with the arm m19 and tends to hold them in the relation shown in Figs. 28 and 30, so that the pinion m15 is permitted through the gear :1:14 to drive the matrix-carrying belt x7 continuously. If, however, a matrix from improper engagement with the distributer-bar or from any other reason is prevented from advancing properly, it will arrest the travel of the carrying-belt and through the intermediate parts arrest the rotation of the gear-wheel whereupon the pinion x15, continuingits rotation, will climb on the gear x14, thereby lifting the arm m19 out of engagement with dog wis, allowing the latter to engage the disk fr, as shown in Fig. 3l, whereby the pinion w15 and attendant parts are brought to a stop, the drivingbelt in the meantime slipping on the pulley m16. After the matrix has been released by the attendant the latch or dog m18 is thrown by hand out of engagement with the disk w17 and restored to the original position, (shown in Fig. 30,) thereby unlocking the parts, so that the matrix-carrier belt may continue its movement. It will be seen that the foregoing combination of parts constitutes an automatic stop to check the feed or travel of the matrices whenever any undue resistance is oered to a matrix or to the carrying-belt. After one line of the matrices has been delivered the horizontal shiftenslidex is moved back to the left in position to act upon a succeeding line, when it is in turn lifted by the elevator N.

Reference has been made to the fact that while the line of matrices stands before the front of the mold preparatory to the casting operation it is justied or elongated to the predetermined length by the rising of the stepped spacers I through the line between lthe matrices while the latter are held at rest as against vertical motion. This lifting of the spaces may be effected by any suitable mechanism-such, for instance, as that represented by- Letters Patent'of the United States to Ottmar Mergenthaler, No. 565,490. In the drawings, Y and y represent, respectively, the stepped slides and the sector-plate of said patent. The means for operating beveled upper edge of the mold, so that when the mold is crowded forward between these shoulders it tends to bring the matrices in the line into exact alinement vertically.

It is to be understood that the teeth on the upper ends of the matrices for purposes of distribution may be made in any appropriate form. In Figs. 4, 5, and 6 these teeth are shown as beveled or inclined on the under face, while in Figs. 7 and 8 they are shown with horizontal upper and lower edges.

The devices for imparting motion to various parts of the machine will now be described.

The main shaft U is seated horizontally in the main frame and carries all the principal i cams for giving motion to the other parts, as

shown in plan View in Fig. 3. On one end this shaft has fixed upon it a gear-wheel u, which receives motion from a pinion u on an underlying shaft u2, mounted horizontally in the main frame and havinga limited end motion. The pinion u' is formed on one end of `a sleeve (see Fig. 38) which surrounds the shaft and is connected thereto by a longitudinal spline or feather, so that the two are compelled to rotate together. On the outer end of the sleeve there is mounted a loose pulley a3 to receive the driving-belt. For the purpose of connecting this pulley with the shaft when the parts are to be driven I provide a clutch consisting of a hub n4, pinned fast to the shaft and jointed to two radial outwardly-extending links U5, the outer ends of which are in turn jointed to friction-shoes u, acting against the inner surface of the rim of the driving-pulley, these shoes being sustained and guided on radial spokes or arms, so that when the shaft u2 is drawn forward endwise it causes the shoes to firmly engage the rim of the pulley, sothat rotary motion is imparted through the clutching devices from the pulley to the shaft and to the pinion and cams thereon. A spiral spring @t7 encircles the shaft-bearing between the inner side of the pinion and a collar u8, fixed to the shaft. This spring tends to urge the shaft forward and keep the clutch in engagement. For the purpose of permitting the operator tothrow the clutch out of action and to stop the machine at will the eccentric hand-lever a9 is pivoted to the front of the frame within convenient reach of the operator and arranged to act on the forward end of the shaft to press it backward. As the machine completes at each revolution of the main shaft all the op- IOO IOS

erations necessary for the completion and delivery of one slug, it is necessary to automatically throw out of action at the finish of each revolution all the cams and other parts for imparting motion to the mold, casting mechanism, ejector, dye. This is effected by providing one of the cams, preferably the potactuating cam p5, (see Fig. 38,) with a pivoted dog uw to act on the inclined surface on the side of the shaft-collar ns, whereby the shaft u2 is automatically pushed endwise to disengage the clutch. hen the machine is to be started, the dog n10 must be moved out of engagement with the collar, and this is effected, as shown in Figs. 37 and 38, by a sliding bar uw, connected to a hand-lever uw and held normally backward out of action by a spring um. By moving the hand-lever the bar may be thrust forward, so as to push the dog 'am out of engagement, whereupon the spring n?, before referred to, will cause the rengagement of the clutch. From the foregoing it will be understood that the main shaft is automatically stopped at the coinpletion of each revolution and that it is in the power of the operator, by means of the handle a9, to stop the machine at any time. The release of the handle a9 will cause the machine to start from any position except that in which it is arrested by the automatic stop. The matrix-lifting device of the distributing mechanism has its pulley mi driven by belt 1321, extending across the top of the machine and downward over idler-pulleys to a pulley m22 on the shaft which carries the pulley at the upper end of the assemblingbelt F. (See Fig. l.) These parts must be kept continuously in motion, and they will therefore be driven from a constantly-running driving-pulley, a belt being preferably eX- tended from the pulley @t3 to a pulley on the shaft which carries the lower pulley of the assembler-belt. It is to be understood, however, that these driving connections are not of the essence of the invention and that they may be modified at the pleasure of the skilled mechanic.

The melting-pot P is swung upward and forward toward the mold by means of the lever p4, turning on a horizontal shaft (see Figs. 3, 37, and 38) and acted upon at its rear end by a depressing-cam on the main shaft, this cam being so formed that the pot is swung upward and held against the mold the proper length of time and. then permitted to fall backward therefrom.

The pot or pump plunger p2 for delivering the molten metal is operated by a verticallyvibrating lever p6, (see Figs. 37 and 33,) urged constantly downward by a spring p", and lifted at the proper times by cam ps, mounted in the main shaft and acting on the rear end of the lever.

The devices for moving the mold and the ejector-blade have already been described.

The operation of the machine as a whole is brieiiy as follows: The finger-keys being manipulated in the proper order, matrices and spacers are delivered from their respective magazines into the assembler G, wherein they are assembled in close order. When the line has reached such length that the introduction of an additional word or syllable is impossible, the device M is operated to grasp the line and transfer it to the left from the assembler G into the elevator N, after which the transfer device is permitted to return to its first position to resist the matrices for the next line, the elevator N is lowered to present the matrices in front of the mold, the devices Y and y thrust the spacers I upward through the line to effect its justification, and the pot and the mold move forward until the mold is in intimate contact with the matrices and the pot in intimate contact with the back of the mold. Vhile the parts are in this position the pumpplunger descends and molton metal is delivered into the mold against the matrices, thereby forming a slug or printing-bar with type in relief on its forward edge. The pot retreats from the mold and the mold retreats from the matrices, withdrawing the slug. The mold swings upward carrying the base of the contained slug past the stationary knife Q, by which it is trimmed to the proper height. The mold stops behind the knives R R and in front of the ejector-blade S, which, advancing from the rear, drives the slug out of the mold and between the knives R R, which trim it to the proper thickness, the advance of the slug being continued until it is in front of the stationary lever T, by which it is delivered into the galley. In due time the ejector-blade is withdrawn and the mold descends again toits operative level. While the other operations are progressing the elevator N carries the line of matrices and spacers which has been used from the casting-level upward, the lower forward member of the elevator being arrested in its ascent with the spacers thereon, so that they will be transferred to their magazine, while the matrices are carried to a higher level and into the path ofthe slide 00, by which they are urged to the right and against the lifting device, which serves to raise the matrices one at a time from the line into engagement with the fingers of the feeding-belt, by which they are carried forward along the distributer-bar until they escape therefrom into their respective channels in the magazine.

W'hile I have represented the stepped spacers herein, it is to be understood that they are not a necessary feature of my machine, as they may be replaced by other known forms of justifying devices-for example, the ordinary double-wedge spacers, such as shown in the Sehuekers and Mergenthaler patents and now in general use in the Mergenthaler linotype-machine.
